This small plant with proportionally large flowers was known to occur in the northern parts of the South American Continent, but recently the species was found as south as in the Brazilian State of Bahia. The flowers found there have thinner segments and are not so graceful as the northmost parents. The genus has some twenty species, not often seen in cultivation. These plants have fan-like arranged leaves and no pseudo bulbs. They are epiphyte and the growth habit is sympodial.
The flower has a intriguing sac like lip with a frontal hole.
